#
#  Makefile for the Duktape development repo
#
#  This Makefile is intended for ONLY internal Duktape development
#  on Linux (or other UNIX-like operating systems), and covers:
#
#    - building the Duktape source distributable
#    - running test cases
#    - building the duktape.org website
#
#  The source distributable has more platform neutral example Makefiles
#  for end user projects (though an end user should really just use their
#  own Makefile).
#
#  YOU SHOULD NOT COMPILE DUKTAPE WITH THIS MAKEFILE IN YOUR PROJECT!
#
#  Duktape command line tools are built by first creating a source dist
#  directory, and then using the sources from the dist directory for
#  compilation.  This is as close as possible to the sources used by an
#  end user, at the risk of accidentally polluting the dist directory.
#
#  When creating actual distributables, always clean first.
#

# Scrape version from the public header; convert from e.g. 10203 -> '1.2.3'
